sAsII-IIOLDER.

T0 all wzom'z't may concern.' Y j Be it known that I, JAMESP. WILLIAMS,

a citizen of the-United States, residing aty New York, in thev county of'N ew York and State of New York, have invented certain. new and usefulImprovements in Sash- Holders; and I do declare the ,following to be -afull, clear, and eXact'description of the invention, such as will enableothers skilled in the art to whiclrit appertains to kmake and use thesame.

rIhis invention relates to improvements inL windows and more especiallyto sash holders.

The object of the invention is toprovide.`

simple and eficient means for permitting a window sash to be raised andlowered and tof frictionally hold it in adjusted position.k

Another object of the'invention is to pro-P vide a simple and eiiicientdevice for positively retracting said sash holder and for holding it inretracted position.

With these and other objects,y in viewthe invention consists-0f certainnovel features of construction and the combination andarf rangement--okf parts as will be more fully.

described andfclaimed.`

In the accompanying draw1ngsF1gure 1 represents a front elevationV ofawindow equipped with this improvement; Fig.-2`is a detailverticalsection'al view onan enlarged scale showing more particularlythe-.means for frictionally engaging the sash withnthe frame; Fig. 3 isasimilar view with the holder in retracted inoperative position; Fig. 4is an edge View ofthe sash showing more particularly the device forfrictionally connecting the sash with the frame; Fig. 5 is a detailhorizontal section taken on the line 5 5 of Fig. 2*; Fig. 6 is asimilar. View taken on the line 6-6 of Fig. 1; Fig. 7 is a detailvertical section taken on the line 7 7 of Fig. 5.

In the embodiment illustrated a window frame A of ordinary constructionis Shown provided with the usual sash retainingstrips B between whichthe sashes C are At both Sides of the frame sash guides are shown in theform of ver-V tically disposed laterally spaced angle irons 1 on thelaterally extending flanges 2 of which the Sash are designed totravel.One

` side of the sash C is equipped with a plurality of longitudinallyspaced grooved guide engaging members herein shown in the form vofblocks 3 having grooves 4 therein and l Specification of Letters Patent.Appiieation fired Augustin, 1914; serial No. 856,039.

which are positioned to slidably engage the i Harige-s 2 of the guides lon the adjacent side of the frame and which aredesigned to provideforthe free vertical movement of this side-ofl the sash onsaid guidesandwhereby the sash is held against lateral movement.` The oppositesideof the sash C havs'longi-V tudinally spaced recesses 5 and 6 ,withv asolid portion or block 7 between them which is cut away on its kouterface as shown at 8 suiiiciently to receiveand house a portion of theholderconstituting this invention and which will now be described.

This improved holder comprises a spring metal ystrap 9 securedintermediately of its ends preferably midway thereof to the outer ablemeans.k Peripherally grooved friction rollers 1,0k and `11 are pivotallymounted on thefree `endsof 'the strap 9 and are adapted when desired ,tobe retracted and Yhoused face of the block 7 by Screws or other suitywithinv the; recesses y5 and 6 vof, the sash by A means to be described.These rollers 10 and 11 are normally held by the resiliency of the g.

strap 9 projected into frictional engagement with one of the :fianges` 2of the guidesv l'on l the, adjacentside ofthe `frame, The y resiliencyof this strap 9 is such as to cause said rollers to engage saidiiangewith' a' suii'icient amount of frictionto support the `sash. towhich-the holder is attached in any desired position and yet which willyield to` permit the rollers to travelon said flangel when force isexerted on the sash to raise or lower-it. Extending through said strapends adjacent the".r rollers 10 and l1 `are threaded eye bolts or ears12 equipped on the ends adjacent the frame A withwing nuts 13. Slottedlinks 14 are connected tok the outer ends of these eye bolts 12 andproject through apertures 15 in the side members of the sash C as isshownclearly in Figs. 2 and 3. Disposed over these apertures on theinner face or edge of these side members of the sash are L-shapedbrackets 16 one arm or plate 17 of which covers the aperture 15 overwhich it is disposed and the other arm 18 extends laterally out at rightangles to said face. The arms 17 of the bracket 16 are apertured asShown at 19 to permit the passage therethrough of the n Y allyprojecting arm 18 of each bracket 16 is an eccentric member 2O having anoperating arm and a cam portion 21. This eccentric member is pivoted tothe outer end (See Figs. v2, 3 and 5). Hence it will be Y observed thatwhen the levers or arms 20" Y are turned in onedirection as shown inFig.

2 the pivots 22 which kconnect the members 20 with the links 14 will bepositioned near the inner ends of the slots 14 which permits the forceof the spring strap 9 to be exerted to force the rollers 10 and 11carriedV on the free ends thereof outward into frictional engagementwith the flanges 2 of the guides -1 on the adjacent side member of thewindow trame as is shown clearly in Fig. 2.

Vhen for any reason it is desired tofdisengage the rollers 10 and 11from the guide flanges the levers or arms 20 are swung in the oppositedirection as shown in Fig. 3 whereby the pivots 22 are forced intoengagement with the outer ends of the slots 14 in the links 14and'thereby move said links outwardly, carrying Vwith them the rollerson the free ends ofv the strap vand these rollers will be held inretracted position untilthe lever is againqturned in theopposite-direction. The wing nuts and eye bolts may' be adjustedrelatively t0 each other to vary the ylength of the links 14 and hencethe extent of retraction of the rollers i *Y by Ysaid links.

'From' the foregoing description it will be obvious that when the levers20 are in the position shown in Fig. 2 to release the rollers andrvpermit them to 'rictionally engage the guide flanges 2, the windowsash to which this holder is attached may be raised or lowered byexerting anupward or downward pressure thereon as desired which willCause the rollers to travel onsaid flanges and theblocks 3 to travel lonthe la'nges2 at the opposite side of the frame and when pressurey on thesash is removed the force of the spring 9 will exert suiiicient pressureto hold` the rollers in frictional contact with the flanges 2 againstthe weight of the sash.

I claim as my invention:

1. A sash holder comprising a resilient strap adapted to be fixed to theouter edge of one or' the side bars of a window sash, a friction rollercarried by said strap, and roller retracting means connected with saidstrap and comprising a slotted link, and an eccentric havingl a studslidably engaged with the slot of said link.

2. rlhe combination with a window sash having a recess in the outer edgeof one of its side members, of a resilient strap fixed to said edge withits free end extending into said recess, a friction roller mounted onthe free end of said strap, an eccentric pivoted on the oppositeedge ofsaid side member, and a link connecting said eccentric with said strap.1

3. The combination with a window sash having spaced recesses in theouter edge of one'of its side members, of a resilient strap securedintermediately of its ends to said edge between said recess with itsends disposed opposite said recesses, rollers on said strap ends, linksadjustably connected with .said strap ends, and having longitudinalslots therein, said sideV member having apertures extending through therear walls of said recesses, brackets mounted on said side members oversaid 'apertures and having openings registering with said apertures, theslotted ends of said links extending through said apertures andopenings, and'members eccentrically fulcrumed on said brackets andpivotally connected with the slotted ends of vsaid linksat points remotelfrom their fulcrums. f

In testimony' whereof' I have hereunto set my hand in presence of twosubscribing witnesses, f
